The study on relation between GCM precipitation data and ground observation data and development of a correction method of GCM precipitation data -Case study in the Yoshino River Basin-

Abstract

The frequency and intensity of strong precipitation will increase globally under the climate change projection. From FY2007, Public Works Research Institute started the research to evaluate the flood risk globally under the climate change projection. The output of the atmospheric general circulation model (AGCM) which has been developed by Meteorological Research Institute is used in the project. In this study, the relation between AGCM precipitation data and ground observation data in the Yoshino River Basin was examined and a correction method of AGCM was developed.
